PAPER-SEVERIN G ATTACHMENT FOR PAPER-BOX MACHTNES.

Specification ,of Letters Patent.

Patented July 16,1912.

Application filed July 15,1909. serial no. 507,718.

Be it known that we, F.nw1N J. SCHOETTLE and CHARLES A. GARRE'IT,citizens of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a certain newrovement in Paper-severing Attachments or Paper-Box Machines, of whichthe following is a specification, reference being had therein to theaccompanying drawin s..

Our invention has for its object an improvement in attachments to beused in connection with paper box machines (and more particularly inconnection with the so-called Its particularobject is to provlde meansby which a strip of paper, such for instance as the cover paper, shallbe automatically severed along the proper line without the necessity ofthe operator making a movement either with thehand or foot especiallyfor this purpose, thereby saving to the operator a considerable amountof time and lessening the fatigue incident to the operation performed.

Our device is adapted particularly for use 'in covering machines inwhich the box or other article to be covered is supported upon arestduring the operation.

ur invention provides means by which the pressure which the operatorputs upon the box when attaching the corners of the covering paper tothe front corners of the box depresses the rest and causes the cuttingattachment to sever the paper at the proper point. The paper which isthus severed from the web falls upon the box and is then rubbed down byhand in the usual way. It will be seen that our invention relieves theoperator from the necessity of cutting off the paper by a separate footor hand operation.

While we have described our invention in the following specification asapplied particularly forbox covering machines, we believe that it iscapable of application to other kinds of paper box machines and ac--cordingly do not limit ourselves to the particular application of theinvention shown.

The invention will be fully understood from the followihg descriptiontaken in connection with the accompanying drawings, and the novelfeatures thereof are pointed out and clearly defined in the claims atthe close of the specification.

Referring to the drawings,- Figure 1 is a side elevation of a machineembodying our invention showlng also the support for the form on whichthe box is placed during the.l

covering operation. Fig. 2 1s a similar view showing the position oftheparts at the time that the cutting operation'takes place. eferringnow to the draWings,-at 11 is shown the head upon which is supported arock-shaft 12 to which the rest 13 for the box form 14 (see Fig. 2) isfixed. The rest 13 is ad ustable by means ofthe bolt 15 and thumb screw'16. rocker arm 17 fast on the rockshaft 12 is connected by a link 18 tothe slotted cross-head 19 sliding in .Ways 20 on the head 11 of themachine. The said cross-head 19. is slotted as shown at 21 and theposition of the link 18in relation to the said cross-head 19 isadjustable by means of the hand-screw 22. To the lower end of thecross-head 19 is pivoted a link 23 connected at its upper end to one armof a bell crank lever 24 pivoted at 25 to the head 11 of the machine.The other arm of the bell crank lever 24 is connected by a link 26 tothe arm 27 of a rockshaft 28 supported in a bracket 36 on the head 11 ofthe machine. Fast on said rockshaft 28 is a gear 29 meshing with a gear30 on a second shaft 31. Said shafts 28 and 31 .are each provided withjaws 32 and 33 which are substantially crescent shape and are providedat their extremities with cooperating cutters 34 and 35 respectively.Said cooperating cutters are pivoted for the purposes of adjustment tothe respective jaws 32 and 33 at 37 and 38 respectively and are fixed inany desired position by means of the set screws 40 and 41. The parts areheld with the jaws normally separated as shown in Fig. 1 by means of thespring 42 attached at one end to the arm 27 of the rockshaft 28 and atthe other end to a bracket 43 onthe head 11 of the machine. Adjustmentis provided by means of the screw 44. and check nut 45.

- The paper from the roll of the cover machine is shown at 46 in Fig. 2,and it will be seen that the parts are so located that the cutters 34and 35 come together on substantially-the line on which the paper isdrawn from the reel on which it is wound in the cover machine. The boxrest 13 is so located With relation to the position of the cutters atthe pointwhere they come together that the desired length of paperrequired to cover the box is severed by the cutters from the web ofpaper. This adjustment may be waste of paper is reduced.

paper and then causes In the operation of the machine embodyourinvention, the operator seizes the end 1n of' the web of paper takingthe two corners thereof between the thumb and forefinger of each hand.He draws out the paper from the web, and then presses the paper whichhas been previously provided with adhesive down upon the two frontcorners of the box which is upon the rest. This moves the restdownwardly thereby drawing out the paper somewhat farther owing to thelocation of the respective parts relative to each other and near the endof the said downward stroke the cutters operate to sever the paper atthe right point. The operator then rubs the severed portion of the paperdown upon the box in the usual manner.

What we claim is:

1. A paper severing attachment for paper box machines comprising a pairof tpivoted jaws on opposite sides of the strip 0 paper, each of saidjaws having a cutting edge, both of saidjaws being movable and adapt edto meet centrally and sever the strip of paper, a rest for the boxmovable downwardly from its normal position and connections between thesaid jaws and the said rest whereby the downward movement of the restcauses the said jaws to meet cen-. trally and sever the strip of paper.

2. A paper severing attachment for paper box machines comprising a pairof pivoted jaws on opposite sides of the strip of paper to be severed,each of said jaws havingfi cutting edge, a rest for the box mova ledownwardly from its normal position and connections between the saidjaws and the said rest whereby the downward movement of the said restfirst draws out the strip of the jaws to meet centrally and sever thestrip of paper.

3. A paper severing attachment for paper boii machines comprisin jaws onopposite sides 0 to be severed, each of said 'aws having a cutting edge,a pivoted rest or the box below and beyond said jaws arid movabledownwardly from its normal position and connections between the saidjaws and the said rest whereby the downward movement of the rest firstdraws out the strip of paper and then causes the jaws to meet centrallyand sever the strip of paper.

4. A paper severing attachment for paper box machines comprising a pairof pivoted jaws on opposite sides o the strip of paper to be severed,each of said jaws being provided with cutting edges, a rest for the boxa pair of pivoted the strip 0t paper below and beyond the said jaws andmovable downwardly from its normal position and connections between thesaid jaws and the said rest whereby the downward movement of the restdraws out the strip of paper and severs the strip of paper while beingdrawn out.

5. A paper severing attachment for paper box machlnes comprising movablecutting mechanism, a pivoted support for the box, a support for saidpivot adjustable vertically a cross-head, an adjustable connectionbetween said pivot and said cross-head and connections intermediate saidcross-head and said movable cutting mechanism whereby said movablecutting mechanism is actuated by the movement of said movable support,

and the position of the' pivoted support may be adjusted with relationto the said cutting mechanism.

In testimony whereof we affix our signatures, in presence of twowitnesses.
